Zombie, that is a bright light! However, I was looking to get away fro having another battery to charge. Mr. Jones, I have never had any issues with sparking when plugging in my headlight. The only way(s) it could spark is if the 2 conductors were somehow shorted. Those plugs are designed to be plugged in "live". I do have a pushbutton switch mounted to my handlebar for lights on and off, and keep it off when I plug in, for whatever that is worth. Again, I have the ability to energize one of the 3 lights, which is mounted in the same place as the original, for general night time riding, focused on the ground about 50' in front of me, as to not blind auto drivers. I only energize the other 2 when on the beach or golf course at night. They could blind an oncomming driver!
